CTO Advisory
An experienced outside perspective when the stakes are high.
Even the best internal technology leaders benefit from a trusted outside perspective. Our CTO Advisory service gives your technical leadership access to senior, battle-tested guidance on the decisions that matter most — without the overhead of a full engagement.
The Short Answer
CTO Advisory gives your existing technology leader — or your CEO and board — access to a senior, independent technology executive for strategy pressure-testing, architecture reviews, build-vs-buy decisions, and due-diligence support, without a full engagement. TrailMark offers it as a monthly advisory retainer starting at $2,500/month or as project-based support, with a one-month minimum.

CTO Advisory — Frequently Asked Questions
- How is CTO advisory different from a fractional CTO?
- A Fractional CTO owns and drives your technical direction and leads the team day to day. CTO Advisory is lighter-touch: an experienced outside perspective that supports your existing leaders on the decisions that matter most, without taking operational ownership.
- What does CTO advisory cost?
- TrailMark's Advisory Retainer starts at $2,500/month (4–8 hours) for ongoing decision support, or it can be scoped as a fixed project. Minimum one-month commitment.
- Can you support technical due diligence for a fundraise or acquisition?
- Yes. We provide independent technical assessments, architecture narratives, and Q&A preparation for investment rounds, M&A, and board reporting — from either the investor or the company side.
